Status trap
A Status trap is generated when an error condition occurs on a tower, infeed, Environmental Monitor or individual
sensor. Status traps include the reported status, the location of the PDU, and identifier/name of the affected tower,
infeed, outlet, environmental monitor, or sensor.
Any error state generates a Status trap and triggers the trap timer. A new trap is generated at the end of every timer
period until the Status returns to a non-error status. All status traps are enabled by default.
